You certainly mean '\n' at the end of the string, not plain 'n'.

Other than that, this need for parentheses would be a bug. gettext for C
certainly does not require the outer parentheses. Maybe the pure-perl
implementation in libintl-perl-1.16/lib/Locale/gettext_pp.pm requires them?
Maybe Guido Flohr can say something about it?
